Can you tell if very many surfaces have the green and magenta reflections? My 50mm Summicron M defintely has yellow and magenta reflections, and a hint of green off the front element when I hold it just right. My 35mm Summicron M has all yellow reflections, but with one definite green reflection deep within the lens.
